Autism is a spectrum of disorders that affect social and communication skills. There are many types of autism with varying symptoms. While it was once believed that autism was caused by bad parenting or vaccines, studies have found no link between autism and vaccines or parenting.

Current estimates find that about 1 in 150 people live with an autism diagnosis.
